In two of my birthday celebrations, I was awake from around 12:00am - 2:00am and slept by 10:00 pm to 12:00 am of the next day. So, thankfully, it's 24 hours or less.
Man, I can't believe there are actually people here who have stayed awake for more than a day. Seriously, people, you really have to catch some sleep. That's not healthy, especially for your brain.
